This repository contains the full PDF of an academic research paper examining the architectural transformation of Microsoft's ERP platform from Dynamics NAV to Dynamics 365 Business Central.
The motivation was straightforward: after years of doing NAV-to-BC migrations and explaining the architectural difference to clients and colleagues, I wanted to write something rigorous about it, not another "top 5 reasons to move to BC" post, but a proper architectural analysis with theoretical grounding, real citations, and an honest take on the trade-offs involved.
The paper traces the full story: from Navision's origins in the 1980s, through the Microsoft acquisition, through the C/AL monolithic object model and the upgrade debt problem it created, all the way to Business Central's Azure-native architecture and the event-driven extension model that makes continuous SaaS delivery possible.
Historical context, Navision → NavisionDamgaard → Microsoft acquisition → Dynamics NAV branding → Dynamics 365 Business Central
NAV architecture deep-dive
- The C/AL programming language and its database-native record model
- The object model: Tables, Pages, Reports, Codeunits, XMLports
- How direct object modification worked and why it accumulated technical debt
- The upgrade burden: why major version upgrades became months-long projects
Business Central architecture
- Cloud-first design on Azure Kubernetes Service
- Multi-tenant SaaS delivery model and what it demands architecturally
- The AL language, VS Code tooling, and Git-native development workflow
- The extension package system and compatibility validation layer
Event-driven extension model
- Publisher-subscriber pattern in AL
- Business events vs. integration events vs. database triggers
- How the isolation between base application and extensions makes automatic updates possible
- AL code examples and event dispatch flow diagrams
Comparative analysis
- Side-by-side comparison across 9 dimensions: architecture type, customization model, deployment, scalability, integration capabilities, upgrade process, tooling, version control, security
- Honest discussion of where BC constrains you compared to NAV and why
Literature review drawing on IEEE, ACM, Springer, and HBR sources alongside Microsoft technical documentation, connecting the platform evolution to broader software engineering theory (Parnas 1972 on information hiding, Hohpe & Woolf on enterprise integration patterns, and others)
- BC developers who want to understand the platform more deeply than "write extensions, not modifications"
- Solutions architects evaluating NAV-to-BC migration projects
- ERP consultants who need to explain the architectural shift to technical stakeholders
- Researchers in enterprise software architecture or ERP systems
- Anyone who has sat through a painful NAV upgrade and wondered why it had to be that way
